WASHING-MACHINE.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed March 22, 1905. Serial No. 251,372.

To all whom, it may concern:

Be it known that I, WVILLIAM MILLER DIGIIT, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inVVashing-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My present invention relates to improvements in washing-machines, andhas special reference to a device in which a plunger is reciprocated insuch a manner as to receive air therein on the upward stroke and poundthe clothes and expel the air on the downward stroke, so as tothoroughly cleanse the clothes and agitate the water.

To attain these objects, the invention consists of a novel constructionof washing-machine, as will presently appear.

In the accompanying drawings, Figure 1 is a vertical central sectionalview through a receptacle, showing my mechanism in position for use.Fig. 2 is a perspective view of the plunger and operating mechanismremoved from the receptacle. Fig. 3 is a side elevation of thesupporting-plate for the operating mechanism.

Referring to the drawings, the numeral 1 designates the receptacle,which has secured upon the interior thereof near the top, by means ofstaples 2, the supporting-plate 8, which is provided with openings 4 forthe reception of the staples and with a series of curved adjusting lugsor projections 5, which are adapted to receive the lower end 6 of theprojecting support 7, which is provided with the bifurcated upper end 8,in which is pivotally mounted the operating lever or handle 9. he innerend of the handle 9 is provided with slot 10, which alines substantiallywith the center of the receptacle and is adapted to receive the upperend of the pounder-rod 11, which is provided with openings so that anydesired adjustment can be had to accommodate the clothes within thereceptacle. Carried upon the lower end of this piston-rod is a pounder,which consists of a series of cylinders 13, each one of which aresecured tobinding or solder, and are provided with the closed tops 14and the open bottoms 15. By this construction it will be seen that asthe lever 9 is reciprocated the pounder is also reciprocated within thereceptacle and that upon each upward stroke a certain amount of air isdrawn within the cylinders and when the cylinders are forced downwardthe air is expelled simultaneously with the pounding of the clothes,thus insuring a double action upon the clothes, so as to thoroughlycleanse the same.

From the foregoing description, taken in connection with the drawings,it is evident that I provide a washing-machine of this character whichis in its embodiment simple, durable, and inexpensive and which is athoroughly efficient and practical device.

What I claim as new, and desire to secure by Letters Patent, is-

In a washing-machine, the combination of a receptacle, asupporting-plate secured within the receptacle near the top thereof,said supporting-plate being provided wit-h a series of curved adjusting-lugs providing spaces therebetween, a vertical support providedwith a projecting lug adapted to fitin the spaces between the projectinglugs to hold otally secured to the upper end of said vertical support, apounder-rod adjustably secured to said lever intermediate of its lengthand projecting into the receptacle, and a pounder carried by the lowerend of said rod, said pounder consisting of a series of cylindersprovided with open bottoms.

In testimony whereof I aflix my signature in presence of two witnesses.
